The Benefits of Upgrading to Low-E Glass in Leesburg Homes

What Low-E Glass Actually Changes

Low-E glass gets its name from its low-emissivity coating, which slows the movement of heat through the window while still letting in natural light.

The coating works quietly, but the result is noticeable, especially in rooms that get blasted with afternoon sun or sit above a chilly basement.

That matters in Leesburg, where a house can face hot, humid afternoons, then turn around and feel cold and drafty a few months later.
